Hi Charlieg83,
I would like to welcome you to our online community

I am sorry to hear though about the difficult situation with your sister. Has she been diagnosed with BPD and/or perhaps any other disorder? Has she ever gotten any professional help for any of her issues?
Very sorry to hear also about your mother's stroke. That's quite a difficult thing to deal with
It is sad that your sister seems to be in a negative spiral.
She has just messaged me telling me to leave her alone so should I just leave her to it or try and push through? She has done this before and come out of it but it was hard work.
When you say it was hard work, do you mean hard work for you getting through to your sister? Or are you talking about that it was hard work for your sister coming out of this?
Take care
The Board Parrot
